Abstract: A method of preventing and controlling corrosion and build-up of scale in cooling-water systems at water temperatures below about 212.degree. F. The method comprises the use of an effective amount of hydrogen peroxide, i.e., 0.01 to 100 parts by weight per million parts of water, about 0.01 to 100 parts by weight of at least one organic triazole per million parts of water, 0.1 to 200 parts by weight per million parts of water of at least one polymerized ethylenically unsaturated carboxylic acid, e.g., polymerized maleic acid having average molecular weights ranging from about 250 to 500,000 and 0 to 200 parts by weight, e.g., 0.1 to 50 parts of at least one non-ionic surfactant.

Abstract: This invention relates to a combination of anionic and nonionic polymers and surfactants useful for the control of dust emissions into the environment. More specifically, the invention relates to novel compositions and the use of said compositions in treating particulate matter which comprises an aqueous solution of water-soluble polymers comprising a unique mixture of water-soluble anionic acrylic polymers in combination with water-soluble nonionic glycol polymers in an aqueous medium containing effective amounts of an anionic surfactant such as the sulfonates and a nonionic polyalkoxy alcohol cosurfactant.
